.ple and economical of manufacture.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing in which:-

Fig. 1 is a plan view of a card of impression trays embodying my invention.

Fig. 2 is a view in perspective of a tray adapted for application to the small toe area.

Fig. 3 is a similar view of a tray shown applied to the central toe area.

Referring more particularly to the drawing, the numeral Ill refers to a card assembly of impression trays formed preferably of cardboard having an absorbent quality. The board II] is scored as at H, l2, l3, l4, l5 and I6, to form 3 separate impression trays I1, I8 and IS.

The tray I'l forms a receptacle for casting material used on the great toe area of the foot. The member l8 forms a foldable tray adapted for casting in the middle toe areas of the foot. The portion I9 is especially designed for casting in the little toe area of the foot.

The tray I! has an opening in the center thereof substantially of an elongated egg-shape with one side thereof having a more pronounced curve for its accommodation against the plantar surface of the foot, the tray being so marked adjacent said edges. The opposite side of the opening is adapted to rest against the dorsal side of the foot and is so marked. The outer edges of the tray are marked anchor, and at such points are adapted to be secured to the foot by means of adhesive tape. The small end of the eggshaped opening 20 is to be disposed forwardly of the foot when the tray is in place.

The tray i8 is scored at 2|, 22, 23 and 24 so that it may be folded at these points, and the small sections 25 and 26 between the folds may be rested respectively against the plantar and dorsal portions of thefoot behind the toe which should be cast as in Fig. 3. 5

The portion I9 is similar to the portion I1, but is smaller in size adapting it more readily to casting in the small toe area.

In Fig. 2 the tray 19 is shown in place about the small toe area. A prop 29, formed of a portion of the board is inserted between the small toe and the tray I9 at a point abutting the adjacent toe.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, all within the scope of the apparent claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:-

1. A device of the class described comprising a tray having a central elongated egg-shaped opening, one side of the formation surrounding said opening having a relatively greater curvature adapted for application against the dorsal surface of the foot with the opposite side of said opening having an edge adapted for placement against the plantar surface of the foot.

2. In a device of the class described, an impression tray adapted to be folded at two points medially thereof, with the inner faces of the portions between the folds adapted by reason of their configuration for placement against the dorsal and plantar surfaces of a foot, in the operation of casting.

3. In a device of the class described, an impression tray having an opening therein and adapted to be folded at two points, with the inner faces of the portions between the folds adapt- 40 ed by reason of their configuration for placement against the dorsal and plantar surfaces of a foot, in the operation of casting.
